"Motivation is not a fixed construct. Teachers can use their understanding of motivation and encouragement to improve literacy practices, achievement and students' perceptions of their abilities"

Motivation Misconceptions:

Motivation is just something kids have or develop. Some kids are motivated and some are not.
Motivation reflects a sort of self-discipline. Some students have to persevere or work harder than others. Regardless of tasks and instrumental factors, some kids are just more determined.
Motivation is perceived by students as some kind of immediate encouragement that suddenly sparks their interest and activity.
Motivation is a diminishing, nonrenewable resource. If you lose it with a group of kids during a given year, it may be gone for good.
